Stove is a GE Adora Model JBP63HH2bb. It took me forever to figure out how the burner was attached to the rails.
My glass top was different than any instructions found on the internet for changing out a burner. The burners on this one are held to the bottom of the glass cook top by two rails that cross the bottom of the burner assemblies. In order to get too the burners you must remove 4 Phillips screws to lower the rails and burners from the cooktop. I suggest two people do this because if the burner fall they can be damaged.
Next you must use a 3/16" nut driver to loosen two spring loaded screws on the bottom side of the rail to release the burner. Make note of the numbered holes on the underside of the old burner so you can use the same ones on the new burner. Now remove the old burned and make the hole to be used on the new burner by drawing a line up the side of the burner so you can locate the holes to be used. (I actually punched the holes so they would line up, only a small punch using one of the hex screws tip) Then line up one hole at a time and get the spring and hex screw in position and hold the burner down on the screw while picking the rail up and using the hex driver to tighten the screw. Do this on the other side then transfer the wires.
Now carefully raise the rail/burner assembly back up to the cook top and re-install the four Phillips screw.

The glass was easily replaced. Just a few screws to remove cover then remove bad glass then i dropped in the replacement glass then reinstalled cover. Ithen put the door back in the stove. 15 minute job!!! I was so surprised to see how easy it was!!! Thanks! Part fit perfectly!!!
